A coulomb is a measure of charge and current is the rate of flow of charge.
There is a formula linking the three quantities (charge=Q; T=time; I=current):
Q=I x T -> 1.5A x 0.1s= 0.15C

Kicking Horse Pass is the highest point on the Transcanada Highway.
AC can pass through a capacitor. The higher the frequency of AC the lower the reactance (like resistance). The current and applied voltage are 90 degrees out of phase the current leading the voltage by this amount.
Yes and no. A capacitor generally does not pass DC current, except for a small "leakage current", but upon the inital application of a DC voltage, the capacitor will pass current until it reaches the full potential of the applied voltage. The simple answer is no it does not. In fact we use that characteristic to "decouple" one circuit from another in amplifiers for example.

Here we are given 3.1 amperes of current and are asked to find the time it takes 10 coulombs of charge to pass a given point. First ask yourself how many coulombs are passing a given point in one second. If we have 3.1 amperes of current, we have 3.1 coulombs of charge passing any given point in one second. If it takes 1 second for 3.1 coulombs of charge to pass, how long will it take for 10C of charge to pass?
Current = charge/time = 10/5 = 2 amperes
If you divide the charge by the time, you get the average current (in amperes).
(4 coulombs / 2 seconds) = 2 coulombs per second = 2 Amperes.
2 amperes
The current is calculated by dividing the charge (6 coulombs) by the time (2 seconds). Therefore, the current is 3 amperes (6 coulombs / 2 seconds = 3 amperes).
1 Ampere = 1 Coulomb/sec (225 Coulomb) / (5 sec) = 45 Coulomb/sec = 45 Amp.
Divide the coulombs by the amperes. The answer will be in seconds. The resistance is irrelevant in this problem.
To calculate the time it takes for 9 coulombs to pass a current of 3 amps, you can use the formula: time = charge / current. Plugging in the values, time = 9 coulombs / 3 amps = 3 seconds. So, it would take 3 seconds for 9 coulombs to pass a current of 3 amps.
72 coulombs in 24 seconds is 3 amperes.One ampere is one coulomb per second.
Electric current (in amperes) is calculated by dividing the electrical charge (in coulombs) by the time taken (in seconds) for the charge to pass through a given point in a circuit. The formula is I = Q / t, where I is the current, Q is the charge, and t is the time.
In the formula for electric current (I = q/t), q represents the amount of charge passing through a point in a circuit, measured in coulombs. t represents the time taken for the charge to pass through that point, measured in seconds. Electric current (I) is the rate at which charge flows through a circuit.
